| Phone number | to | Phone | Required |

Setup
Step-by-step setup
Connect, map your fields, place a test call, and switch on production sync to HubSpot.
Connect your account in KaiCalls using OAuth, API credentials, or the approved webhook path for the platform.
Map caller fields to the destination fields your team already uses for intake, sales, or service handoff.
Set trigger rules for when KaiCalls should create a new record, update an existing record, or only attach notes.
Place a test call and confirm the record appears with the expected name, phone, inquiry type, summary, and transcript.
Enable production sync, then review the first real calls for duplicate handling and required-field coverage.
What syncs
What gets synced to HubSpot
Standard fields sync every time. Conditional fields only sync when the caller provides the data or your team enables the corresponding rule.
| Data | Destination | When it syncs |
|---|---|---|
| Caller identity | Contact record | Always sent |
| Inquiry type | Contact property or deal property | Always sent for qualified calls |
| Call notes | Timeline activity | Always sent for completed calls |
| Source campaign | Attribution property | Sent when tracking data is present |
| Lead score | Custom property | Sent when scoring rules are enabled |
Troubleshooting
Common mistakes and troubleshooting
The usual snags when wiring up a new sync, and how to clear them fast.
Leads are not appearing
Confirm the connection is active, the write user has create-record permissions, and the trigger rule is enabled for qualified calls.
Duplicate contacts are being created
Match existing records by normalized phone number first, then email when present. Keep the platform's duplicate rules enabled.
Mapped fields are missing
Check whether the destination field is required, hidden, renamed, or restricted by permissions before changing the KaiCalls mapping.
Sync is delayed
Review provider rate limits, webhook retries, and workflow queues. Native writes should be near real time after the call ends.
FAQ
HubSpot integration FAQ
Answers to the questions teams ask before connecting KaiCalls to HubSpot.
How long does it take to connect KaiCalls to HubSpot?+
Most teams can connect KaiCalls to HubSpot in under 10 minutes once admin access is ready. The longest step is usually confirming which required fields your team wants populated before production sync is enabled.
Does the HubSpot integration create duplicate contacts?+
KaiCalls checks for an existing contact by phone number before creating a new one. If a match exists, KaiCalls updates the existing record with the latest call summary, transcript, and qualification details instead of creating a duplicate.
What caller data syncs to HubSpot?+
Caller name, phone number, inquiry type, call summary, call transcript, and lead score can sync to HubSpot. Optional fields such as appointment time, source campaign, and practice area can be added when those fields exist in your workspace.
Do I need HubSpot's API or enterprise plan to use this?+
Contact creation can work on lower HubSpot tiers, but custom properties, deal automation, and workflow triggers may require a paid HubSpot tier depending on your portal configuration.
Can I customize which fields map to HubSpot?+
Yes. KaiCalls can map captured call data to standard fields and custom fields in HubSpot. During setup, you choose which fields are required, which are optional, and which values should only sync when the caller qualifies.
Can KaiCalls trigger HubSpot workflows after a call?+
Yes. Once KaiCalls creates or updates the contact, your existing HubSpot workflows can route the lead, notify staff, create follow-up tasks, or move the record into the next pipeline stage.
